MACHINE FOR MAKING BOTTLE-SEALS.

Specification of Letters Fatent.

Application filed June 13, 1916. Serial No. 103,577.

To all whom it may concern Be it known that I, ALFRED H. BRAECK- LEIN, a citizen of the United States of America, and resident of the city of Baltimore, State of Maryland, have invented certain new and useful Improvements in Machines for Making Bottle-Seals, of which the following is a specification.

This invention relates to a new and improved machine for making seals or envelops of the general type described in my Patent No. 1,145,666. These seals are of paper and in the nature of a complete covering for the bottle. As shown, they are tapered to fit the bottle and have the mouth or opening at the end which corresponds to the bottom of the bottle, the bottle being inserted top or open end first and the covering sealed at the bottom to inclose the bottle.

Important features of the invention are found first, in the combinations of parts which go to make up the seal-making machine which is entirely automatic so that it requires no attention Whatever except the provision of the necessary paper stock; second, feature or features of the machine whereby all the operations incident to the manufacture of the seal are accomplished by rolling contact of the parts so that any desired speed may be attained without loss of efliciency or variation in the uniformity or quality of the product; and third. the folders or mechanism for operating the folders to form the tapered container are novel and important to the result obtained.

In the accompanying drawing, l have illustrated a machine embodying the features of my invention.

Figure 1 is a side elevation of the machine; Fig. 2 is a view of the feeding, cutting, scoring, pasting and doubling rollers in their operative relation; Fig. 3 is a view at right angles to Fig. 1, taken from the delivery end of the machine, the drier mechanism, etc., being removed. Fig. 4- is a side elevation of the folding rollers; Fig. 5 is an end view showing particularly the gripping mechanism of the doubling rollers; Figs. 6,

7, and 8 are elevations of the cutting, scoring and pasting rollers respectively; Fig. 9 is a transverse section through the upper cutting roller; Fig. 10 is a transverse section through the upper scoring roller; Fig. 11 is a transverse section through the lower a plan of a blank cut by the machine ready for folding and pasting; Fig. 1-3 illustrates the fold at the top of the seal; and Fig. 142 shows the same fold partly open.

Referring to the drawings by numerals, the machine consists of a frame 1 support ing the various parts which accomplish operation of cutting, scoring, gluing, to 1 mg and pressing the blank into the form oa completed envelop or seal.

Referring to Fig. 12, the blank which is of a length equal to the circumference one cutting roller is several times as long as its greatest width and cut with a slight projection 24 at one end and a concavity 25 at the other. W hen formed into the seal, the blank is doubled about the sverse score 26 at the center and. the for ends makes it convenient to g ll the ha or envelo) at the ooenjnt and been b i o for about oneuarter of the len th of the blank being straight, that is, having itsltwo sidespaa'allel and tapering from this ppint inward to the center score at 26. The ltrqo halves of the blank oiteachsi'cle of the center score 26 are, in the formation of the finished seal, folded together and one-half is ma larger than the other to provide a fiapto folded over the smaller half and pasted. this Way the meeting edges are closed. T e marginal flap or flaps (one on eacl v are indicated by reference character 27 in the drawing. This flap or margin 2'? is uniform width at all points from the end. edge 25 to a point adjacent but spaced from the center score .26. [it this point it is widened to form an extra wide ortion 28 and there is a flap 29 on the other half of the blank continuous with the flap 27 but shown as less than half the width and tapering to point a short distance from the center line. The flaps 27 and 29, illustrated and described, are defined by scoring along the lines 30 and in the completion of the seal, the two halves are folded one on the C no feed, cutting, scoring roller, etc; Fig. 12 is a other, the flaps 28 andflt coming into eon- Pa'tented 5,

slightly folded over together on to the smaller portions of the blank, the pasted edge along the entire lateral in 1,214,5o4

tact and allowing a considerable margin of the flap 28 beyond the flap 29, it beingunderstood that these flaps are all paste-coated. It will be apparent that the flaps 27, being then folded over the smaller half of the blank, a paste-coated margin extending edge of the larger half is brought into contact with. the inner or smaller half of the blank and pressed against it.' When the paste is set, the seal is completed. The object in providing the flap 29 and the wide fiap 28 is to form tight corners by folding two thicknesses of the paper at the top overon themselves, as illustrated in Figs. 13 and 1 1. It will be clearly understood from this illustration that after the two halves of the blank have been folded, one on the other, the edge flaps 27 and the flaps 28 and 29 overlying each other, are

of the flap 28 extending beyond the flap 29 and being thus secured to the face of the smaller or liaple'ss portion of the blank. In this way, we have a closed corner and a finished seal which is not only germ-proof but completely watertight and prevents the entrance into the bottle of any waterwhich may get on the top of the seal. 1

Referring now to the drawing of the ma chine, at the left-on the rear end of the frame is a bracket 2 on which is. supported a roll of paper 3 in the form of a web, indicated by reference character l. Pi'votally mounted on the frame near the top of the paper roll is a frame 5 carrying a guide or take-01f roller 6 which rests by gravity on the top of the paper roll and serves as a means for leading the Web from the roller 3 and directing it upward toward the functioning parts of the machine. The web is drawn bif of the roller by tension applied as hereinafter described, passing around the guide roller 6 and cansing the guide roller to rotate clock-wise, or to the right, while the stock roll rotates contraclockwise, or to the left. From the guide roller 6, the paper web is led to the feed rollers 8 and 9 which have their axes parallel to the axis of the stock roll and are mounted in suitable bearings 8 and 9 in the frameof the machine near the top. The upper bearing 9 is made adjustable by means of a block 10 carrying the bearing proper, resting on a spring 11 andforced downward by means of screw 12. Thus the grip of the feed rollers is positive and adjustable. from the stock roll'and feed forward to the cutting, scoring and pasting rollers, etc. All the rollers, with the exception of the stock roll 3 andthe, guide roller 6 are driven from therotating shaft 13 which carries a toothed gear 11 meshing with a gear 15 on the shaft.

. 16 of one of'the cutter rollers 20 and 21 to be described. This gear in turn meshes with any multiple of the length of a blank, is 7r The feed rollers draw the paper an idler 17 which engages and turns a toothed gear 18 on the bottom one of the feed rollers. This gear meshes with toothed gear 19 which turns the top feed roller. The cutting rollers 20 and 21 are parallel to the feed rollers, preferably in the same horizontal plane, and spaced forward a convenient distance. The upper roller, which may be of a circumference equal to the length of or mountedin an adjustable bearing 22, similar to the bearing 9 described in connection with the upper cutting rollerand both rollers are driven from the gear 14 on the shaft 13, the gear 15 which meshes withthe gear 14: being secured to. the lower cutting roller and meshing with a gear 31 rigidly connected to the upper cutting rollei.

The blank to be cut is shown in plan in Fig. 12 and the cutter 23 is arranged in the 5 form of the outline of the blank with a small opening or gap 23 to provide for a connecting web between the blanks. The cutter consists of a sharpened ridge on the cylindrical surface of the roller 21 outwardly or 9 radially disposed. The lower roller 20 is plain and the cutting operation is performed by the contact of the edges of the cutters on the upper roller with the cylindrical surface of the lower roller through the paper which 5 is passing between them.

Next beyond the cutting rollers in the direction of the travel of the paper which is from left to right in Fig. 1, are the scoring rollers 34 and 35, mounted in suitable bear- 10o ings 36 and 37, the lower bearing being stationary and the upper one adjustable after the manner of the bearing ofthe upper feed and cutting rollers. These rollers are driven by gears 32 and 33 rigidly connected to the lower and upper rollers or the shafts thereof, respectively, the" gear 32 on the lower roller meshing with the gear 14: on the shaft 13.

Scoring is accomplished by means of a blunt edge 38 on the upper roller which is pressed against the paper as it passes between the upper and lower scoring rollers, serving to compress the fibers along the line of the edge 38 and thus score the paper. and make it flexible at the score without cutting it. The scoring edge is arranged on the surface of the upper rollerin the pattern indicated by dotted lines 30 in Fig. 12 and the scoring rollers are preferably made of a circumference equal to the length of the blank as, are the cutting rollers, so that one blank is cut and scored at each revolution of the two sections of the rollers.

Next beyond the scoring rollers in the direction of the feed are the paste rollers 40 and 41 mounted in bearings 42 and 43 for the upper and lower roller respectively, the lower bearing 43 being stationary and the upper one 42 adjustable as in the case of the bearings of the other. top rollers already de- 30 scribed.

To this end, the blade 61 is swung backward by the contact of the arm 62 with the dog leaving an opening between the blade and the forward edge of i-he slob no at the time the two approach she rom'ulon of the roller, this opening serv to receive the blade 69. The relelion rollers the preceding rollers such that the blank traveling forward direction of the throiw'h the machine arrives with its central porlaion, indicated by the line 26, in Fi 2 direc'liybeneath the blade 69 and over the forward porsion of the sloi; 60 between the b 63. and the forward edge of the slot 60 when. the blade 69 1s about "so enser described, the

curvature of the rollers causes be Withdrawn from the slot el s; of "she paper 1e slot 60. To

\ econ-- stunt action, a wear plate73 has been provided. With the paper thus gripped, the roller 50 Continues to rotate carrying the edge of the blank forward along the circumference of the roller 50 until it approaches the line of contact of the roller 50 with the roller 56. Just as the folded edge of the paper enters the grip between the rollers, the arm 62 of the stud 58 comes in contact with the stationary dog or swinging the blade 61 backward and releasing the grip on the folded edge of the paper so that the doubled blank is carried downward between the rollers 50 and 56. In order that the paste on the edges of the blank may not be smeared and the whole operation upset, the roller 56, as well as the roller 50, is made sufficiently short to engage the blank between the paste-coated edges. After being separated from the web by the cutter 75 on the roller 51 which engages the cutting block Y6 on the roller 50 severing the connecting web between the present blank and the one next following which web is left by the cutters on the cutting roller 21, the doubled blank with the paste-coated edge flaps 27 still exposed is fed downward between the rollers 50 and 56 to the folding rollers and the guides or plows 81.

The foldin rollers 80 consist of a series of four pairs of rollers, the axes of each pair being in the same horizontal plane and the rollers of each pair being inocontact, the contact lines of the various pairs of 'rollers be ing in the same vertical plane. As shown, the rollers of the upper three pairs 82, 83 and 84: are of the same diameter, the rollers of the lower pair being larger; To attain and maintain the desired degree of pressure between the rollers, the bearings of the forward roller of each pair are made adjustable toward the other roller, as by means of screws 86. The blanks are guided in their downward course from the doubling rollers by means of parallel vertical guide rods 87 spaced apart'by a sufficient interval to.per- Init the blanks to pass freely between them. In order to feed the blanks downward during the folding operation through the rollers with certainty, and to prevent buckling and wrinkling, it is necessary that the contact points of the rollers shall be as near together as possible and to this end, the rollers are dovetailed into each other, as shown in Fig. 3. The rollers 82 have each a central section of full diameter of length a, the rollers 83 have two narrow sections of full diameter 6, c on each side of the sections a of the roller 82, and the rollers 84; have a central section 62' of full diameter corresponding to the central sections a of the rollers 82 and likewise fitting in between the full diameter sections 7) and c of the rollers 83. The central full diameter sections a and b of the rollers 82 and 8d are slotted to receive the guide rods 87. The rollers 85 each havetwo full diameter sections 6 oncach side of the center, spaced apart to admit the full diameter central sections 03 of the rollers 84 and of sufficient width to permit them to roll the flaps in folded position.

The plows or folding guides 81, see Figs. 3

the edges of the blanks in question, see Fig.

12, are straight near the two ends, the blank tapers from the points 89 about one-quarter. the length of the entire blank from each end to the central. line 26 on which the blank is doubled so that the flaps 27, referring now tothe blank as being doubled and moving forward with the folded edge 26 forward, first diverge at an angle of 20 to 30 degrees and then from the point 89 to the bottom of the seal which in the present operation is at the rear, they are parallel or straight so that it is necessar to provide means for folding the flaps 2 first where they converge and then where they change direction and run straight, parallel to each other, it being understood that the inner flap 29 is turned with the adj accnt contacting portion 28 of the flap 27.

In order to provide for the change of direction of the flap 27 from the diverging portion to the straight or parallel portion, it is necessary to make a corresponding change in th relation of the folding means. This is done by swinging the plows through an angle corresponding to theangle between the parallel and converging portions of the flap. To this end, the plows are mounted to swing and change the direction of the crease which marks the juncture of the flap with the flat portion of the blank so that this crease Wlll follow the score as shown in Fig. 12, the

lower ends of the plows where the turning of the flap is completed having a nearly parallel motion so the point of folding and tits relation to the roller are not changed. This is accomplished by means of a sliding link 92 on each side" which operates in a guide 93 in the frame, the links having each a follower 9d at one end which engages a cam 95 on a shaft 96 driven by suitable gears 97 which mesh with the gears operating the folding rollers, preferably so that the shaft 96 has a single revolution for each revolution of the feedjrollers and therefore for each complete operation of the machine resulting in the production of a finished seal.

ipraeca The sliding link 92, as shown, is turned up at right angles at the end opposite the follower and carries a pivot 98 by which it is connected to a plate 99, forked or slotted at 100 to engage a stationary pivot pin 101 on the frame, the plow 81 being rigidly secured to the plate 99 by any suitable means, as rivets 102. The follower 94 is held in contact with the cam surface by means of a tension spring d connected at one end to the plate 99 andat the other to a pin on the machine frame.

As 1 have pointed out, the link 92 is a rigid member sliding in a fixed rectilinear guide-way 93 so that all parts of the link 92, including the pivot 98, move in a straight line and as the lower end of the plow is immediately adjacent the pivot 98, the plate 99 being rigidl connected to the plow, said end of the p ow likewise has a substantially parallel motion, the slot'100 moving up and down relatively to the pin 101 to compensate for the variation of the path of the pivot 98 and the point of the plow 103 from a true circular arc. Thus we have not only a cl ange of position but a change of direction of the guide sufiicient to provide for the change irection or angle to each other which the two parts of each flap 27 are set.

It will be noticed that the bottom folder rollers, which may be properly termed pressing rollers 85, have their full diameter sections *6 so placed that they contact directly in line with the ends of the plows so that the blank with the flaps turned over and pasted is received immediately into these rollers which engage the edges, particularly the folded flaps, pressing them tightly into place and completing the operation of the pasting.

From the folder rollers, the seal passes downward between the belt 105 and the drying wheel a small pulley 107 on the drive shaft 108 and passing over guide pulleys 109, 110, 111 and 112, spaced about the periphery of the drying wheel which is driven in any suitable manner, as by a belt 113 from a pulley 1141 on the shaft of the lower doubling roller and train of gearing 115.. After passing around the drying wheel between the drying wheel the belt which servesto hold them in pasted position, the seals or envelope partially dry, sufficiently to keep them in a folded or pasted position until completely dry, and they are accordingly delivered from the machine at the point where the belt passes around the pulley 112.

While the operation of the machine has been brought out in connection with the description, it will be reviewed for the purpose of clearness.

The paper web in the roll 3 is drawn over the take-oft rollers 6 by the feed rollers 8 and 9 whence it is fed to the cutting roll- 106, the belt being driven by I ers shown as equal in circumference to the length of the blank provided with a blade or cutter on the upper roller of an outline similar to the blank as shown in Fig. 12, but having a gap or opening 23 in the transverse portion 120 corresponding to the ends 2 1 and% which, it will be understood, are preferably formed by this single cutting edge severing the rear end of each blank from the forward end of the next succeeding blank. The blanks are intended to be led through the machine, each being drawn forward byv the next preceding and therefore kept connected in the form of a single piece of material until severed by the blade 75 on the folding roller 5 which is of a width equal to or slightly greater than the aforesaid gap in the transverse portion of the blade. From the cutting rollers, see Fig. 6, the blanks thus connected are led forward to the scoring rollers, the upper one of which is provided with a blunt edge in the form of the dotted lines on the blank, see Fig. 12. Th blunt edge is pressed against the paper which is supported on the lower roller compressing the fibers along the line thus-engaged, forming a score or line along which the paper is easily folded without cutting or weakening the fiber. From the scoring rollers, see Fig. 7, the blanks still connected as described, are led to the paste rollers, the

upper roller of which is formed with a raised portion 17, see Fig. 8, conforming to the outline of the flaps 27, 28 and 29 between the dotted lines 30 and the outer edges of the blank. These raised portions are coated with paste by means of the roller d4 fed from the paste pot 15. From the paste rollers, the blanks are fed forward to the doubling rollers and 51 which operate as already described, the center of the blank defined by line 26 in F ig. 12 being gripped by the blade 61 and the forward face of the notch in the roller 50 so'that the creased edge at the centeriof the blank is fed forward and downward between the lower doubling roller 60 and the roller 56, the ends 24; and :25, see Fig. 12, being doubled together and the connection between this blank and the next succeeding blank being cut by the blade 7 5 on the top roller 51 acting in conjunction with the cutting block 76 on the lower roller 50. From here the blank goes to the folding rollers and plows 80 and 81 which turn the edge flaps 27, 28 and 29, already paste-coated as described, along the dotted lines 30 and over the adjacent edges of the smaller and flapless portion of the blank. The blank with the flaps thus folded is then fed downward to the drying wheel, whence it is delivered in finished condition.

I have thus described my invention specifically and in detail in order that its nature and operation may be fully understood;

however, the specific terms herein are used descriptively rather than in their limiting sense and the scope of the invention is defined in the claims.
